IPhone 12's keyboard keeps freezing/doesn't show up in different apps.

IPhone 12. Latest possible update. In many apps where you are able to provide input, the keyboard may freeze or doesn't show up for between a split second and a few seconds. Funny part is that the more updates I install the worst everything going. Reminds me this old class action lawsuit when Apple intentionally slowed down older devices, now it will be adding more glitches to 2+ years old devices forcing customers to get newer stuff?

I understand that apps may exit due to the limited amount of RAM on cheaper versions or I may see slowdowns in not the native browser (yeah everything that is not Safari will work considerably slower) but keyboard functionality is the basics of the phone usage and always, yes always should have higher priority than an app it will be opened in.

So lets see if I am not alone in this.
